Yeah im lucky in that respect too, my mrs has bought me some very nice things for the roadster at xmas and birthday
Spending a little on parts you could have made yourself does speed things up a bit and I must admit im wanting to be ready for the summer, also our baby is due in july so it needs to be finished before then and a nursery decorated
I know what you are saying about getting carried away though, but i have learned from previous projects that using new parts where possible from the start if possible saves alot of agro in the long run.
